LUBRIGATOR FILLER Filed Jan. 5, 1929 4 INVENTOR 2 BENlTO MONTOYA ATTORNEPatented Dec. 30, 1939 PATENT GFFIE BENITO MONTOYA, OF LOS ANGELES,CALIFORNIA LUBRICATOR FILLER Application filed January 5, 1929.

My invention is a lubricator filler, adapted to contain severaldifferent kinds of lubricating oils such as might be required for alocomotive.

My invention may be considered as an improvement on my patent for alubricator, No. 1,596,443 issued August 17, 1926.

An object of my present invention is to use air pressure to expel theoil from a receptacle or tank so that this oil may be utilized forvarious purposes in connection with a locomotive. As for instance,flange oil may be driven to a flange lubricator and valve oil to a valvelubricator.

Another object of my invention is in forcing the oil out of the oilreceptacles or tanks by the movement of the piston and having the pistonrod graduated to showthe amount of oil consumed or the amount left inthe receptacle.

My invention utilizes a housing construction which may be readilyattached to the locomotive boiler, convenient to the auto maticlubricators and preferably above the fire door of the locomotive. Thelubricator has preferably three receptacles or tanks for lubricatingoil, two of which are placed parallel to each other and a thirdreceptacle located midway between the lower receptacles and slightlyabove'these. The air chamber is below the center receptacle and betweenthe lateral receptacles. The pistons are mounted in the lateralreceptacles and are driven upwardly by the air pressure, expelling forinstance flange oil from one receptacle and valve oil from another, to astandard flange oiling device and to a standard cylinder valveindicator.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a plan of my invention taken in the direction of the arrow 1of Fig. 2;

Fig. 2 is an elevation taken in the direc tion of the arrow 2 of Fig. 1,showing the mounting on the rear end of the locomotive boiler;

Fig. 3 is a side elevation in the direction of the arrow 3 of Fig. 2;

provided with discharge pipes 29 which are Serial No. 330,517.

Fig. 5 is a horizontal section on the line 5-5 in the direction of thearrows.

In constructing my invention, the rear plate of the locomotive boiler isdesignated generally by the numeral 11 and to this there is attached'abracket plate 12. This bracket plate supports the housing of thelubricator designated generally by the numeral 13. Within this housingthere are a pair of cylindrical receptacles 14 and 15 which are designedto contain different kinds of oil, for instance, the chamber 14: mayhave flange oil and the chamber 15 lubricating oil. These chambers havea reduced upper section 16, there being shoulders 17 connecting the wallstructures 18 of these receptacles. I i An upper oil receptacle 19 isconstructed between the extensions 16 and has a bottom or floor'20. Thecentral chamber 21 is utilized for the compressed air and operates thelateral lubricating supply.

The lateral receptacles are provided each with a piston 22 having apiston rod 23 extending through ahead 24, the head having suitableleak-proof packing 25. These piston rods'have indicia 26 thereon whichis visible on the portion extending above the heads. A compressionspring 27 is coiled around each piston rod and'bears against the pistonand the head, thus tending normally to depress the pistons.

The lateral tanks have filling cups 28 leading out 'from the upperextension and are adapted to lead to standard automatic lubricatingdevices. For instance, the flange oil may be led to .a standardflangeoiling device'and the valve oil may beled to a cylin- V der valvelubricator such as in the manner illustrated in my patent abovementioned. Below the airchamb'er 21 there is a duct 30 and there is aninlet aperture 31 for air connected to an air supply pipe 32 and anoutlet aperture 33 connected to'an outlet pipe 34: positioned in theduct 30. Inthe bottom of each of the receptacles there is an air port 35below eachof the lateral receptacles 14 and 15, these ports beingpreferably formed in a removable base plate 36 which contains the duct30. Needle valves 37 adjust the openings of the ports 35, therebyconstituting valves for regulating the supply of air to the receptaclesl4 and 15 below the pistons. The receptacle 19 is provided with a fillerplug 38 on the top, this being of a type which may allow the inflow ofair and has a faucet 39 adjacent the bottom. The upper receptacle 19 isdesigned. for engine oil which is free flowing and may be filled by thefaucet 39 into hand oil cans.

The manner of operation and functioning of my invention is substantiallyas follows:

The air may be exhausted fromthe lateral oil receptacles 14 and 15 byopening air relief cocks 40 and when so opened the springs 27 thrust thepistons to their lowermost position and if desired at the same time; oroil may be poured in the filling cups 28. The center oil receptacle 19maybe filled through the filler plug 38, this plug being designed toallow the air to exhaust out of the central receptacle as the oil isfilled in and also to allow air to enter when oil is thrown off throughthe faucet 39.

When it is desired to operate the automatic oil supply to the flangeoiler or the valve cylinder lubricator or both, an inlet valve 41 in theinlet air'supply pipe 32 is opened and the outlet air valve 42 in theair outlet pipe 34 is closed/ Then by the regulation air graduallyforces the pistons upwardly,

expelling the oil in the two lateral oil receptacles, whence such oilmay flow by the pipes 29 to the flange oiler and to the cylinder valvelubricator. The indicia 26 on the piston rods shows the consumption ofoil. The oil is prevented from leakage at the piston rods by utilizingcompression springs 43 mounted in a socket 44 and bearing upwardlyagainst the leak-proof packing 25 held in place by the packing gland 45.

From the above description it will be seen that I have developed asimple lubricator filler which may readily be attached to a boiler of alocomotive and by utilizing the air pressure which is standard on alllocomotives and readily controlled by the engineer or fireman, asufficient supply of oil may be maintained for the automatic lubricatorssuch as the flange oiler and the cylinder valve lubricator. Also asupply of oil may be carried 1cpfinveniently for filling into oil cansorthe Various changes may be made in the principles of my inventionwithout departing from the spirit thereof as set forth in thedescription, drawings and claims;

I claim: 7

1. A lubricator container comprising in combination a body structurehaving a pair of lateral oil receptacles, each having a reduced upperportion, a piston in each receptacle having a piston rod extendingupwardly through the reduced section and through the top of thestructureand each having indicia thereon, a central oil receptacle positionedbetween the two extensions, an air chamber below the central oilreceptacle, a duct having valves leading from the air chamber to thelateral receptacles below the pistons, fillers for said receptacles,discharge connections from the lateral receptacles adapted to lead tolubricators, a filler plug and a discharge faucet for the centralreceptacle, and means to discharge air from the lateral receptaclesbelow the pistons, the air connection from the cylinder to thereceptacles comprising a base plate secured to the said structure andhaving a duct therein, ports in the base plate and controllable valveplugs for said ports, thereby forming valves.

2. A lubricator container comprising in combination a body structurehaving a pair of laterally positioned oil receptacles, each having acontracted upper portion, a piston in the lower portion, piston rodsextending upwardly through the contracted portion and up through the topof the structure, said rods having indicia thereon, fillers for each ofthe receptacles and connections adapted to lead to the receptacles, anair chamber between the receptacles, an air connection from the airchamber to the receptacles comprising a base plate secured to the saidstructure and having ducts therein, ports in the base plate leading tothe receptacles below the pistons, and controllable valve plugs for saidports thereby forming'valves.

In testimony whereof I have signed my name to this specification.
